Impact of the introduction of foreign or new species to an environment?

Question

What is the impact of the introduction of foreign or new species of plants and animals to a different environment and what are the disasters caused by these?

Answer 1

The impact is valid when:

1. The species you introduce is more or at least as successful as the existing same job animals (for example put a tiger in savanna)

2. When the new spices is not influencing others habitat, For example camels in Australia.

Usually when you introduce a computing more successful spices in an area the old one gets extinct. For example marsupial wolf an the new man with hunting dogs. The first ones gone.

  But this is an evolutionary cycle that is normal. But sometimes as case in Australia with rabbit they had to introduce also a hunter fox, to get they're number under control. Like farm with no cat. Eventually you get tons of mouses. This will not be bead if factories transforming them in to kitycat will exist. But now modern cats eat different then old ones.

Answer 2

Supposes the species of Humane, were from Indiana, Idaho, India and .or. Indynesia, wouldn't IT would Be Funtastix, as well, m'Lode ? Example : a Rhino interbreed with an Anoa,

.or. a Giraffe with that of,aaaaarg,say a Comodo, Elephant than Hippopotamus would be in Qasiquasimode as yet.

Wanna TRY some ???!

Answer 3

Introduction of exotics can be either good or bad but is usually bad. For every ring-necked pheasant introduction, we have a dozen bits of idiocy: starlings, giant (Midwestern) Canada geese, house sparrows, purple loosestrife, water hyacinth, multiflora rose, kudzu, nutria, snakeheads, "rabbits" in Australia, grey squirrels in England, gypsy moths, Asiatic bittersweet, mile-a-minute, Poligonum perforatum (sorry, I can't recall the common name ... giant knotweed?) ... The frightening thing is that some of these were introductions made after governmental study of the potential effects.

Answer 4

OK, so first off introduction implies human means. If a speices arrives on an ocean current, blow in by the wind, etc., it is called colonization.

Introduced species are not always bad, but there have been some disasters including: the introduction on mosquitoes (an avian disease vector) from the bilge water of ships causing extinction of countless Hawaiian bird species, the clogging of waterways and decline of local species in the Great Lakes caused by zebra mussels (again, bilge water from Europe) and the compromising of previously productive range for antelope, elk and deer in the west by Eurasian weed species which outcompete natives and happen to concentrate toxins from the soil making them lethal to ingest. There are countless other examples such as: tamarisk in the Colorado River basin, Purple Loosestrife in wetlands nationwide, snakes (forgive me for forgetting the species) in the rainforest on Guam, kudzo in the South.

With introduced species, people never know what will happen. Some of the worst of the aformentioned weeds were imported as pretty garden plants. There are other imported garden plants that are completely harmless.

As for the previous answerer's assertion that it is all cause for survival of the fittest, he might be right in the long term. The problem is that the evolution is an extremely slow process, and the ecosystems affected by the introduced species will be out fo balance for a long time.

Answer 5

The introduction of of new species to an environment has been proven to be disastrous. Animals that thrive without certain predators can become extinct because of an introduction of a predator. Cats rats snakes etc... have all been problems introduced by man. Not every place should have the same pray and predator otherwise the world would become very boring. Look at what was brought to the Native American Indian{small pox}. This caused more deaths then any weapon did.

Answer 6

Gorilla`s running wild in the Rocky mountains would be so cool

Answer 7

I believe it's called evolution and/or natural selection.  It's always happened and it always will, whether it's a result of odd winds or currents carrying seeds, low water creating land bridges, or man made modes of transportation carrying travelers along.  Whether or not it is called a "disaster" is in the eye of the beholder, not nature.

Answer 8

It is normally a disaster for either the existing species or the spcies introduced.  Examples include the deliberate introduction of the rabbit without it's natural predators to Australia, and the Gypsy moth in North America.  The zebra and quagga mussels, the round goby, purple loosestrife, phragmites, giant hogweed and others have infested the part of the United States where I live.

Other introductions have had far less impact, such as Russian thistle, also called tumbleweed, into the American southwest.  All spruce trees are also the descendants of imports as are all starlings.  The camels turned loose in the southwest did not fare anywhere near as well as the horses, which are an import.

Some imports have caused double disasters, such as the disease-bearing rats that escaped from ships onto many of the Pacific Islands.

Answer 9

the problem with most introduced species is that they have no native predators or disease here are just a list of a few famous invaders1)dutch elm disease 2)Asian longhorned beetle 3)round gobi 4)chestnut blight 5)africanized honey bees 6)pigeons 7)starlings 8)German cockroaches 9)Pharaoh ants 10)Gypsy moths  look up these invaders and the carnage that they have brought to this Continent

Answer 10

the asian beatle is a prime example. they invade every crack & crevice of your home & they are almost impossible to get rid of. i did learn 1 thing about them though... they prefer light over dark. i have a house that has a white wall next to a brown wall & during the summer you can see thousands of them on the white wall & less than a hundred 2 feet away on the brown wall.

watch "the simpsons" episode where Bart takes a frog to England. you will have your answer.

have-a-loving-day!
